Indoor positioning has grasped great attention in recent years, a lot of research papers have been published in this field. However, there exists no technology that proves its efficacy in all different cases. This paper presents a complete study for indoor positioning with a proposed solution. the first stage of the study is a comparative analysis of several well-known technologies currently available for Indoor Positioning such as Wi- Fi, BLE or GPS. The second stage is based on the comparison's result of the first stage and decide to use Bluetooth Low Energy (BLE) in my solution. BLE is a very practical solution for indoor positioning systems (IPS) which offers acceptable accuracy and low-cost deployment. In this work, I use Received Signal Strength Indicator (RSSI) to estimate the distance between different devices. In the third stage, signal's RSSI are filtered to increase the accuracy of estimated distance using Kalman filter. Finally, trilateration method is used for estimation the position of devices based on the output of previous stages. Experimental results show that the proposed solution has promising results by achieving a positioning accuracy within 0.76 to 0.39m and average 0.53m.
近年来,室内定位引起了人们的极大关注,在这一领域发表了大量的研究论文。然而,没有一种技术可以在所有不同的情况下证明其有效性。本文对室内定位进行了全面的研究,并提出了一种解决方案。研究的第一阶段是比较分析目前室内定位的几种知名技术,如Wi- Fi、BLE或GPS。第二阶段是基于第一阶段的比较结果,并决定在我的解决方案中使用低功耗蓝牙(BLE)。BLE是室内定位系统(IPS)的一种非常实用的解决方案,它提供了可接受的精度和低成本部署。在这项工作中,我使用接收信号强度指示器(RSSI)来估计不同设备之间的距离。第三阶段,对信号的RSSI进行滤波,利用卡尔曼滤波提高估计距离的精度。最后,根据前几步的输出,采用三边测量法估计设备的位置。实验结果表明,该方法的定位精度在0.76 ~ 0.39m之间,平均定位精度为0.53m,效果良好。

One of the attractive solutions used for supplying low-power medical applications is the photovoltaic (PV) energy harvesting system. In this paper, the proposed PV energy harvesting system is composed of a photovoltaic panel, a DC-DC boost converter, a fixed resistive load and an analog control algorithm. This algorithm is designed based on the output load current. The algorithm is implemented using the multisim program. This algorithm is simple, efficient, low cost and low power consumption because it measures only the output current parameter and does not need multipliers. The power consumption of the proposed load is approximately 39.24 mW. Therefore, the expected working duration of the load is 20.9 hours under continuously operation of the light for 4 hours. Finally, the simulation results illustrate the transient characteristics of the proposed PV system.

A Multi-Label Computer-aided Diagnoses System for Detecting and Diagnosing Diabetic Retinopathy 糖尿病视网膜病变的多标签计算机辅助诊断系统
Pub Date : 2019-12-01 DOI: 10.1109/ICCES48960.2019.9068188

Multi-label classification (MLC) is considered an active research topic, especially in medical image analysis. We used MLC to diagnose the multiple different grades of Diabetic Retinopathy (DR). DR is caused when a patient's blood pressure and blood sugar are too high and results in damage in the blood vessels (BVs). BVs supply the blood to the retina. If the retina does not get the blood it needs, it can eventually cause permanent blindness. The early diagnosis of different DR grades leads the ophthalmologists to efficient treatment. In this paper, we developed a multi-label computer-aided diagnosis (ML-CAD) system to apply MLC for different DR grades using color fundus images. Our system utilizes 11 texture features descriptors by retrieving the average of the Gray Level Run Length Matrix (GLRM) on four directions 0°, 45°, 90°, and 135°. It distinguishes the normal from DR cases by supplying the extracted features to the support vector machine (SVM) classifier. Then, the proposed CAD system segments some significant characteristics from DR fundus images, which are BV, exudates (EX), microaneurysms (MA), and hemorrhages (HM). After that, it calculates the Gray Level Co-occurrence Matrix (GLCM), regions of interest (ROIs) areas, and BV bifurcation point's calculations. Finally, the feature vector is trained and tested using a multi-label SVM (MSVM) classifier generates a suitable DR grade. We used four various benchmark datasets to evaluate the performance of our system in terms of accuracy (ACC), sensitivity (SEN), specificity (SPE), the area under the curve (AVC), and micro F1 measure. The experiments confirmed that our ML-CAD system outperforms the other diagnosing DR systems.
多标签分类(MLC)被认为是一个活跃的研究课题,特别是在医学图像分析中。我们使用MLC诊断多种不同级别的糖尿病视网膜病变(DR)。当患者的血压和血糖过高并导致血管受损时,就会引起糖尿病。血管为视网膜供血。如果视网膜得不到所需的血液,最终会导致永久性失明。不同程度DR的早期诊断有助于眼科医生进行有效的治疗。在本文中,我们开发了一个多标签计算机辅助诊断(ML-CAD)系统,利用彩色眼底图像将MLC应用于不同程度的DR。我们的系统通过检索灰度运行长度矩阵(GLRM)在0°、45°、90°和135°四个方向上的平均值,利用了11个纹理特征描述符。它通过将提取的特征提供给支持向量机(SVM)分类器来区分正常情况和DR情况。然后,提出的CAD系统从DR眼底图像中分割出一些重要特征,包括BV、渗出物(EX)、微动脉瘤(MA)和出血(HM)。然后计算灰度共生矩阵(GLCM)、感兴趣区域(roi)面积和BV分分叉点的计算。最后,使用多标签支持向量机(MSVM)分类器对特征向量进行训练和测试,生成合适的DR等级。我们使用四种不同的基准数据集来评估我们的系统在准确性(ACC)、灵敏度(SEN)、特异性(SPE)、曲线下面积(AVC)和微F1测量方面的性能。实验证明,我们的ML-CAD系统优于其他诊断DR系统。

The proliferation of Social Network Sites (SNS) first appeared globally during 1997 serving intrinsic social communication through SixDegrees.com. However, SNS use was heavily acknowledged in the Middle East and North Africa (MENA) region from 2011 onwards with the rise of the Arab Spring. SNS affect values, beliefs and perceptions of people using them, which are reflected on their attitudes and behaviors towards their surroundings. This paper discusses SNS users' behavioral typology within the context of Egypt's society. The study presented in this paper was based on a survey of 300 participants covering a wide demographic spectrum. The analysis process utilized quantitative and qualitative techniques. The findings of this study contribute towards the development of SNS users' behavioral typology in Egypt after nearly ten years of SNS usage.

the onboard radar is emerging as one of the most practical methods that can be used for identification and many other applications. Nowadays, almost all unmanned applications use onboard radar as a main sensor that provides critical information. Airplanes, satellites and some unmanned vehicles use various kinds of radars sensors depending on the required mission. Imaging radar sensor is used to produce two-dimensional images. It produces its light to illuminate certain area and take a picture at radio wavelengths. This kind of radars produces high quality images with large size. Thus; the produced images must be compressed to reduce their size and decompressed when used. There are different algorithms for compression and decompression, but when onboard, there is a need for an algorithm that will not consume excessive power to save batteries and require less time to be reliable for use. This paper discloses a new methodology for the image compression based upon the compressive sensing techniques., its implementation using the FPGA and the required simulation.

In recent years, ensemble learning methods show great effectiveness in improving model performance in several applications. Ensemble techniques rely on the incorporation of multiple different models together to get one optimal model. The primary assumption of ensemble techniques is that the cooperation among various classifiers will probably compensate for the mistakes of a single classifier and consequently, the ensemble's general output prediction would be better than the prediction of a single classifier. A key issue in the combination of classifiers is the diversity among its members. In this paper, we utilized model averaging as an ensemble learning technique for offline Arabic handwritten word recognition to train three residual networks (ResNet18) models. We demonstrate improvements by incorporating diversity in output prediction by using distinct techniques of optimization. To validate the proposed method, experiments have been carried on the IFN/ENIT (v2.0ple) database which contains 32,492 handwritten Arabic words of 937 unique Arabic words.
近年来,集成学习方法在提高模型性能方面表现出了很大的效果。集成技术依赖于将多个不同的模型结合在一起以获得一个最优模型。集成技术的主要假设是,各种分类器之间的合作可能会弥补单个分类器的错误,因此,集成的一般输出预测将比单个分类器的预测更好。分类器组合中的一个关键问题是其成员之间的多样性。在本文中,我们利用模型平均作为离线阿拉伯手写单词识别的集成学习技术来训练三个残差网络(ResNet18)模型。我们展示了通过使用不同的优化技术将多样性纳入输出预测的改进。为了验证所提出的方法,在IFN/ENIT (v2.0ple)数据库中进行了实验,该数据库包含32,492个手写阿拉伯文单词,其中937个阿拉伯文唯一单词。

Cancer is consider one of the worst disease in the modern era which cause a huge number of deaths each year world wide. It is generated due to the abnormal growth of attacking enormous number of cells to the human body cells that white blood cells can't defend for the human body. Regionally, the number of death as a consequence of the cancer is increasing and affect the growing economies badly. Medical imaging is a technique that visualize the inside of the human body using computerized device. Usually, manipulating the problems of medical imaging using image processing techniques. Leukemia is cancer of the body's blood-forming tissues, including the bone marrow and the lymphatic system. Chronic Myeloid Leukemia (CML) is a type of blood cancer that causes the body to produce a large number of white blood cells. In this research, FISH (Florescent In Situ Hybridization) images is the key factor of detecting abnormalities in genes. FISH usually used for detecting abnormality in chromosomes and DNA features. CML also can be detected using FISH. CML diagnosis depends on the detection of fused Red and Green signals. Our approach first detects FISH signals, their colors, and then fusion between these colors. Moreover, number of fusions need to be counted in order to specify the proper treatment as the number of fusion is important in defining the severity of the case. We prepared our dataset for our own experiment and publish it online for research usage. Our approach experimental accuracy achieved 98% which prove the efficiency of the approach when compared to similar research.
癌症被认为是现代最严重的疾病之一,每年在世界范围内造成大量死亡。它是由于白细胞无法为人体防御的大量细胞攻击人体细胞的异常生长而产生的。就区域而言,癌症造成的死亡人数正在增加,并严重影响到不断增长的经济。医学成像是一种利用计算机设备可视化人体内部的技术。通常,利用图像处理技术来处理医学成像问题。白血病是人体造血组织的癌症,包括骨髓和淋巴系统。慢性髓性白血病(CML)是一种导致身体产生大量白细胞的血癌。在本研究中,FISH(荧光原位杂交)图像是检测基因异常的关键因素。FISH通常用于检测染色体和DNA特征的异常。CML也可以用FISH检测。CML的诊断依赖于检测融合的红绿信号。我们的方法首先检测FISH信号,它们的颜色,然后在这些颜色之间融合。此外,需要统计融合的数量,以便指定适当的治疗,因为融合的数量对于确定病例的严重程度很重要。我们为自己的实验准备了数据集,并将其发布到网上供研究使用。该方法的实验精度达到98%,与同类研究相比,证明了该方法的有效性。
